Told in flashback from the vantage point of a murder trial, the story concerns a female criminal whose face is disfigured by a hideous scar. The plastic-surgery removal of this disfigurement has profound repercussions, both positive and tragically negative. The film's multitude of subplots converge when Conrad Veidt, Joan's lover and onetime partner in crime, is murdered. Melvyn Douglas costars as the beneficent cosmetic surgeon who becomes Joan's lover, while Osa Massen appears as Douglas' vituperative wife.
